In my experience of looking for F Skysavers for June, October, and November of 2007, I see plenty of Skysavers (great!) BUT...almost all have 4+ hour layovers in ATL. No, thanks!

The ones that don't have 4+ hour layovers have 40 mins and I'm not willing to risk that.
I'll keep checking, but I've noticed this for the first time...normally I never have problems.
